Athletics 2, Mariners 1, 13 innings

OAKLAND, Calif. — Josh Reddick's double drove in Jemile Weeks from first and gave Oakland its eighth walkoff win of the season. Oakland's Bartolo Colon allowed a single to his first batter, Dustin Ackley, then retired 17 in a row, before three consecutive singles, starting with Ackley, allowed Seattle to tie it.
